Quiet Waters: Bruce Wayne Predator: 3 Medals: Initiation DLC - Batman Arkham Origins

1st Medal Quickly grapple to the isolated guy on the left side and you should have enough distance for the pounce takedown for the first medal. Quickly go under the grates before the other guys arrive and you should be able to get a grate takedown. 2nd Medal Quickly drop the smoke grenade and you should be able to avoid damage. You need to work fast to get the silent takedown medal before the thermal guy turns on his headset and spot you. 3rd Medal You can immediately hide behind the corner and wait for the remaining guys to come and you should be able to easily do a takedown to score the last medal. The remaining guys should be very easy to dispatch in the smoke.
